Over 50 international scientists gathered at The Second Tsunami Symposium sponsored
by The Tsunami Society to hear about recent tsunami research. Laboratory tsunami
landslide generators developed in Switzerland in the last few years now enable scientists
to measure critical tsunami generation and propagation characteristics, and these studies
have provided the inputs to theoretical models which have successfully replicated
tsunami landslide historical observations. Over the last decade, scientists at the U. S. Los
Alamos National Laboratory and Science Applications International Corporation have
developed a compressible Eulerian hydrodynamic code utilizing adaptive mesh
refinement techniques to solve the tsunami generation, propagation, and inundation
problem in a single, large, three-dimensional, computer simulation using appropriate grid
resolutions and realistic equations to describe the Earth's atmosphere, ocean, and crust.
Symposium scientists presented results from models run for the 1958 Lituya Bay, Alaska
landslide and tsunami, and tsunamis generated by meteorite or asteroid impacts
(http://www.spacedaily.com/news/earthquake-02a.html), that showed remarkable realism
and detail.
The possible role of gas hydrates in contributing to slope instability and inducing tsunami
generation generated much discussion during the all-day workshop. In addition, a
number of papers on tsunami hazards and vulnerability, and tsunami historical events
were presented, including studies in Greece, eastern Canada, Indonesia, Cyprus, Aruba,
Peru, and the U.S. (Alaska, Hawaii).

The Tsunami Society promotes the awareness and mitigation of
tsunami hazards by sponsorship of workshops, meetings and symposia and by the
dissemination of knowledge about tsunamis to scientists, officials and the public in part
through its international electronic refereed journal. The Society provides a focus for
discussion and interactions among its members, government agencies, and the public.
During the Tsunami Symposium, The Tsunami Society elected a new slate of officers
who will hold office until the Third Tsunami Symposium planned for May 24-26, 2005 in
Honolulu, Hawaii.
The Society also established an Ad Hoc Committee on Mega-Tsunamis to evaluate
currently available data and research efforts in response to recent media attention that
erroneously suggested that volcano island flank failures would generate ocean-wide
tsunamis capable of devastating densely-populated coastlines at locations distant from the
source (e.g., across the Atlantic or Pacific Oceans). The Committee, consisting of
George Curtis (Chair), Dr. Eddie Bernard, Dr. Laura Kong, Dr. Charles Mader, Dr. Tad
Murty, and Dr. George Pararas-Carayannis, will develop a scientifically-based position
paper on the occurrences of mega-tsunamis in the past, and the likelihood for such events
in the future.
Dr. Tad Murty, Tsunami Society President, presented Dr.George Pararas-
Carayannis with The Tsunami Society Award recognizing his
outstanding and original contributions to the science of tsunami hazards. Now retired,
but still active, Pararas-Carayannis is a former director of the International Tsunami
Information Center and co-founder and officer of the Tsunami Society. The Tsunami
Society also presented an Award to Tom Sokolowski, current Geophysicist-in-Charge at
the U.S. West Coast / Alaska Tsunami Warning Center, for his leadership in the
development and evaluation of techniques for real-time prediction of far-field tsunami
amplitudes and hazard evaluation.
